Abstract: A fluid delivery system, comprising at least one source of pressurized fluid; and, a pod, comprising, an inlet in fluid communication with the source, a piston in fluid communication with the inlet, wherein pressure exerted on the piston by the pressurized fluid causes the piston to move into at least one reservoir, applying pressure to at least one reservoir fluid disposed therein, an outlet in fluid communication with the at least one reservoir for output of at least the at least one reservoir fluid being pressured out of the at least one reservoir by the piston, a pressurized fluid bypass tube in fluid communication with the inlet at one end and in fluid communication with the outlet at a second end, and, wherein the output at least one reservoir fluid and the bypassed pressurized fluid are combined to form a mixture to be applied at an area of application.

Abstract: A mass and/or spring assisted rupture disc including a holder assembly, a rupture disc assembly having a membrane that is operatively connected with a mass and/or a spring to assist its rupture. The mass and/or spring assisted rupture disc is designed with a mass distribution that uses acceleration forces, which are present in many engineering applications, to aid in the opening. This allows a rupture disc that is more compact and more sensitive than a conventional rupture disc in applications with significant acceleration levels. The added force of both the mass and the spring makes the membrane more sensitive and tunable to rupture across a wider range of pressures.

Abstract: A smart system for oil delivery including a dispenser assembly, a pressure supply assembly, a gearbox assembly, and an electronic assembly. The dispenser assembly including a dispenser. The dispenser being an enclosure with a hollow interior with a valve located at one end. The hollow interior of the dispenser defining a reservoir for the storage of oil or other lubrication fluids. The interior of the dispenser further including a pressure supply assembly. The pressure supply assembly including a spring and a plunger that are oppositely located with respect to the valve within the interior of the dispenser. The electronic assembly includes a flow meter, a solenoid valve, and a microcontroller unit. The electric valve being actuated by the microcontroller unit to allow the pressure supply assembly to expel oil stored within the reservoir via the valve.

Abstract: A system for a decentralized emergency lubrication system including a dispenser assembly, a pressure supply assembly, a gearbox assembly, and an electronic assembly. Self-contained packaged oil delivery dispensers that generate its own pressure supply independent of a pump. It is possible to design systems of these packaged oil delivery systems which are strategically placed in a gearbox housing to provide the optimal amount of lubrication during a loss of lubrication (LOL) event. The benefit of dispensers driven LoL solution is that the technology is decentralized in nature, meaning that the supply of pressure does not rely on a single pump or the plumbing of nozzles to a pump. Dispensers offer system redundancy as well as the option to place satellite units strategically mounted in a gearbox housing.

Abstract: An engine shaft oil dispenser including an oil dispenser operatively connected to a mechanical system. The focus is the novel location and form of the oil dispenser, the delivery mechanism (tubes, passages in dispensers and shafts), as well as the filling mechanism of the annular-shaped dispenser (convenient port locations are provided). The annular-shaped dispenser is herein shown in several embodiments, including in a bearing stack, combined with a compressor/turbine disc/nut, and with various options for filling and feeding of oil. The present invention makes use of sometimes unused space in conventional stacks. The oil dispensers herein described are standalone or are incorporated into existing components. This results in more efficient and compact packaging.

Abstract: A packaged oil delivery with integral flow restrictor including a dispenser assembly and a restriction assembly. The dispenser assembly includes a dispenser that is to be mounted on a mechanical system to enhance lubrication of gears, bearings, shafts, seals, and the like. As elements of mechanical systems often rotate at high/low RPM, the channels are intended to slow/expedite the speed in which oil is passively delivered onto the aforementioned components. The restriction assembly includes channels internally disposed within the dispenser to passively meter the flow of oil being expelled. The speed with which the oil is expelled from the inside of the dispenser is directly related to the length and pattern that the channel has.

Abstract: A packaged delivery for short term lubrication including dispenser assembly, flow control assembly, pressure supply assembly and releasing mechanism assembly. Dispenser assembly includes a dispenser filled with oil. Dispensers can be placed within a shaft, a bearing house and a strut. Pressure supply assembly provides pressure to the oil stored in the dispenser. In one embodiment pressure supply is a mechanical pressure source. In an alternative embodiment, the pressure is a compressed gas. In one embodiment, the releasing mechanism assembly includes a thermal rupture mechanism. In another embodiment, the releasing mechanism assembly includes a mechanical rupture mechanism. Flow control assembly includes analog and digital controls to control flow rate of oil.
